Abstract

Pressurized Drinking Mug with a drinking mug capable of retaining a liquid. The mug has an attached hollow handle. The mug also has a removable, replaceable lid. The hollow handle contains a standard air pump mechanism that creates positive air pressure inside the mug. The lid has a liquid retaining reservoir that has a rigid straw portion extending down to the bottom of the mug and also extends upward to a removable replaceable flexible straw. The flexible straw is capable of being pinched closed or opened by a pinch valve so that when the pinch valve is opened, the liquid is forced up through the straw to the user's mouth. The rigid straw portion also contains a side port that can be restricted by a removable, replaceable plug. The port is also capable of retaining a push button valve that allows the pressurized liquid to be pumped into the reservoir.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
       1. Pressurized Drinking Mug comprising: 
       a drinking mug capable of retaining a liquid;  
       said mug having an attached hollow handle;  
       said mug also having a removable, replaceable lid;  
       said hollow handle containing a standard air pump mechanism;  
       said pump capable of creating positive air pressure inside said mug;  
       said lid having a liquid retaining reservoir;  
       said reservoir having a rigid straw portion extending down to the bottom of said mug;  
       said rigid straw portion also extending upward to a removable replaceable flexible straw;  
       said flexible straw capable of being pinched closed or opened by a pinch valve so that when said pinch valve is opened, said liquid is forced up through said straw to the user's mouth;  
       said rigid straw portion also containing a side port;  
       said side port capable of being restricted by a removable, replaceable plug; and  
       said side port also capable of retaining a push button valve that allows said pressurized liquid to be pumped into said reservoir so that the user can drink a small portion of the said liquid while the major portion of said liquid remains inside said mug.  
     
     
       2. Pressurized Drinking Mug as claimed in  claim 1  wherein said pump is a piston type pump. 
     
     
       3. Pressurized Drinking Mug as claimed in  claim 1  wherein said pump is a rubber bladder type pump. 
     
     
       4. Pressurized Drinking Mug as claimed in  claim 1  wherein said mug body is comprised of a double walled construction to provide insulation. 
     
     
       5. Pressurized Drinking Mug as claimed in  claim 1  wherein said drinking mug allows a person to drink liquid from a straw without the act of sucking.
